Quote by: Milton Bradley  The bit I don't get is about pollution.
I was under the impression ( from government information ) that the internal combustion engine produces the bulk of it's emmissions upon start up. After the catalitic converter warms up, the emmissions are filtered.
So, how is requiring the driver to start this engine many times in one trip going to reduce pollution? |
Idle and startup are the least efficient moments in the use of an internal combustion engine (gasoline that is, diesel is more efficient at idle)
Starting up the car uses 10 seconds worth of idle wasted fuel. Idle itself is wasteful because it is wasting fuel with no gain other than powering the comfort controls inside the car.
